Abstract

An electric rotating machine includes a stator 10, a rotor 20 inserted in a bore of the stator 10 such that an air gap is formed between the stator 10 and the rotor 20, and a plurality of permanent magnets embedded in a peripheral portion of the rotor core of the rotor 20 in a circumferential arrangement. Slits are formed in portions of the rotor core 21 each extending between the adjacent magnetic poles. Compressive stress is induced in portions of the rotor core 21 each extending between the slit and the permanent magnet when stress is induced in the portion of the stator core 11 extending between the slit and the permanent magnet by centrifugal force produced when the rotor 20 rotates and acting on the permanent magnet and a pole piece covering the permanent magnet.
